\pplication September 1, 1938, Serial No. 227,938

3 Claims.

The invention relates to lubricating devices, and more particularly, itrelates to a pad comprising a body of absorbent material havingcapillary properties and adapted to carry the oil contents of a carjournal box to the journal.

The pad herein illustrated and described is of the same general type asthat shown in the co-pending application of Aldred J. Jones, Se-

rial No.` 54,231, filed December 13, 1935, nowy Patent No. 2,132,420 forCar journal lubricators, of which this application is a continuation inpart.

The invention has among its objects the provision of improvements in apad of the kind described adapting it to be held against the journal tobe lubricated in a manner such that the pad has uniform capillarity andan even bearing surface in contact with the pad. The pad is adapted tobe suspended from a suitable holder with its lower end immersed in thelubricant,

`the bearing surface of the pad being maintained in contact with thejournalby the holder. Uniform delivery of the lubricant over the bear-.ing area of the journal obviously requires that the pad have an evenjournal bearing surface and that its connection with the holder be suchas not to interfere with the capillary travel of the lubricant to thebearing surface. Any direct connection of a holder or pressure platewith the journal contacting portion of a pad necessarily producesdepressions in the journal contacting surface of the pad and alsointerferes with its capillary action at the points of connection.Journal lubricating pads as heretofore constructed have had theirjournal contacting or lubricating portion directly connected with aholder or with a pressure plate by rivets, staples, stitches or similarmeans which provide recesses in the delivery face of the pad and alsointerfere with capillary action at such points. It is found in practicethat car journals lubricated by such pads have bright annular bands orareas corresponding to such points of connection which indicate thatsuch areas are insuiciently lubricated, and that the deficiency inlubrication is very pronounced on high speed equipment. The inventioncontemplates the provision of a pad having a fold, flap or othersuitable element positioned between the journal bearing portion of thepad and the holder and with which both the holder and the pad areconnected. the pad proper being thereby suspended from and indirectlyconnected with the holder with the result that the pad has the requisiteeven journal bearing surface and uni- (cl. s-.243)

form capillary action and the thrust of the holder is uniformlydistributed over that portion of the pad in direct contact with thejournal.

Another object of the invention is the provision of a pad of increaseddurability, this being accomplished by providing a cover for the padexcept at the journal bearing portion. The pad is quilted to givesuflicient rigidity to prevent the wick material from bunching wheninserted in the journal box. A cover of tough, durable material not onlyprolongs the useful life of the pad, but also facilitates its renovationby preventing dirt, grit and other foreign contents of the lubricantfrom working into the absorbent material. A further advantage of thecover is that it prevents direct frictional contact of the absorbentmaterial with the journal box which would otherwise tend to abradecertain areas thereof and also minimizes or prevents injury to theabsorbent material through the inadvertent using of a hook or pointedtool in the journal box.

Still another object of the invention is the provision of a pad of thekind described which is durable, inexpensive to manufacture and install,and so constructed that it remains completely saturated without waste ofthe lubricant.

Many other objects and advantages of the construction herein shown anddescribed will be obvious to those skilled in the art from thedisclosure herein given.

To this end, the invention consists in the novel construction,arrangement, and combination of parts herein shown and described andmore particularly pointed out in the claims.

Pig. 6 is a view similar to Fig. 5 illustrating a modiiled form of padconstruction; and 5 Fig. 7 is a view illustrating a modified form of padholder.

Referring now more particularly to the drawing, the numeral I5 generallydesignates a pad embodying 'the principles of the invention. The padpreferably consists of a plurality of strands or rovings II of cotton orsimilar material having a high degree of capillarity and each acting asan individual wick extending the full length ofthe pad. The individualrovings II are substantially rectangular in cross section and are heldin closely spaced juxtaposition by a plurality of transverse lines ofstitches I2 having a spacing of approximately the width of the rovings.Lines of stitches I3, respectively extending between the contiguousrovings, are interwoven with the stitches I2 and cooperate therewith togive a quilted effect to the rovings. The

rovings II are preferably of relatively loose texture to facilitate freeilow of oil to the journal. The stitches I2 are sumciently taut toimpart a uniform slightly quilted effect to the rovings II without,interfering with their capillary action.

The rovings II, having been connected as described by the stitches I2and I3, fabric sheets .I4 and I5 arefastened thereto to provide a cover,the sheet Il preferably extending the full length of the rovings on theback side and around the top and downwardly on the front side to form aborder Ila. 'I'he sheet I5 extendsfrom the bottom of the rovings andterminates at a distance from the marginal border Ila to provideasubstantial transverse gap in the cover. The edges of the sheets I4 andI5 are folded and overlap at the edges of the rovings so as to form`ahem I6, the overlapping portions being connected by lines of stitches16a extending through the pad, all preferably in a manner such that therovings are completely covered except at the gap adjacent the topportion of the pad where the hem is omitted. The pad is strengthened andgiven substantial rigidity by providing transversely and diagonallyextending lines of stitches designated by the numerals I1 and I3,respectively, which extend through and connect the opposite cover sheetsI4 and I5. The main body of the pad quilted as described is easilyinserted in a journal box without bunching and is adapted to bend toconform to and lie on the bottom of the journal box I9, as shown inFig. 1. The fabric sheets I4' and I5 are preferably constructed of duckor similar durable material adapted to prevent foreign particles fromentering into the rovings and which is resistant to abrasive wear and isnot easily torn by inadvertent engagement therewith of a hook or otherpointed tool.

The gap between the marginal border Ila and the top of the sheet I5provides an uncovered area of the. rovings adapted to be positioned indirect uniformly pressed contact with the journal 20, as shown in Figs.1 and '1. The gap in the fabric cover is desirable since it isfound inpractice that lubricant collects on the fabric and tends to cake and thefabric thereby becomes impervious to oil if it is maintained in directpressure contact with the journal.

The pad has a width corresponding to the length of the journal bearingrequiring lubrication and the width of the gap between the border Ilaand the sheet I5 is sulcient that neither the lflap or fold 2Ipositioned oppositethe uncovered portion of the rovings, the fold beingfastened to the body of the pad by means of stitches 22 which maybeomitted if desired. A bar or plate 23 connected with the fold 2|provides a connection of the fold witha pad holder and maintains the padwith the uncovered rovings II pressed against the journal 23.

One form of pad holder, mounted in the journal box Il, comprises ahorizontal rod 24 suitably fastened to the box, and a verticallyextending member 25 having its lower end forked and turned to provideeyes 25 through which the rod extends. The bar 23 is pivotally connectedwith the member by a pin 21 extending through'- loops or eyes 23provided by the upper end of the member. A plurality of transverselyextending metal bands or strips 25 are mounted on and fastened to theplate 23 by rivets 30 extending through the fold 2|, the middle portionof the bands or strips being'curved to provide sockets through which thepin 21 extends. The pad is easily detached from the holder by moving thepin 21 longitudinally to disengage the member 25. 'The pin 21 isnormally held against longitudinal movement by providing one end with alaterally extending stem 3| and by providing the corresponding end ofthe plate or bar 23 with a projection 32. The stem 3| -may be formed bybending the pin 21 and the projection 32 is preferably formed bybifurcating the end of the bar or plate 23 and bending the lowerbifurcated portion outwardly. The pin 21 is normally positioned as shownwith the stem 3I lying inside of the projection 32, the projectionserving as a stop permitting removal of the pin only by rotating it toelevate the stem above the projection.

The supporting member 25 is inclined upwardly and inwardly toward thejournal 20 whereby the weight of the pad tends to press it against thejournal. The pressure of the pad on the journal due to the weight of thepad is increased by means of a weight member 35 eccentrically mounted onan inclined rod 35, the rod being rigidly connected with or forming anextension of the member 25 and extending through a slot 31 in the p'ad.The weight of the member 34 increases the pressure of the pad againstthe journal, the amount of such pressure being varied and maintainedconstant as desired; by shifting the member along the rod 35 andfastening it in adjusted position by means of a set screw 35. The

1 rod 35 is relatively narrow and the slot 31, y through which therodextends, is formed bepad is such that it contacts with thefull'length 7 5 of the bearing area of the journal. The rovings beingsubstantially rectangular-in cross section and in close lateraljuxtaposition, the pad thereby provides a continuous arcuate lubricatingsurface constantly pressed against the journal 20. The provision of thepressure bar 23 and the fold 2| are important features of the inventionsince they cooperate to hold the pad uniformly against the journal. I'heheads of the rivets 30 compress the fold 2| substantially in a smallarea immediately surrounding the rivets as is best shown in Fig. 5 whichillustrates the position of the fold when the pad is detached from theholder. The pressure exerted on the fold 2| by the bar 23 when the padis in operative position compresses the fold and flattens its innersurface so that the fold and the rivets have equal bearing on thejournal contacting portion of the pad.

A modified form of pad is shown in Fig. 6 as providing a pad section 38similar in all respects to thevfold 2| shown in Figs. 1 to 5 except thatthe rovings Il are discontinuous, and bending thereof at the top of thepad is avoided. The fabric cover I4 is preferably continuous andconnects tion -being preferably held in position by stitches 22 in thesame manner as shown for the fold 2|.

If desired, the section 38 may be formed separate being completed byconnecting the section withv the body of the pad by stitches 22.

An alternative form of pad holder is shown in Fig. 7 as comprising amember 39 mounted in and fastened to the journal box I9 by a pluralityof bolts 40. The top of the member 39 is forked with its forked portionsrespectively forming eyes 4|, positioned between the middle and the endbands 29 carried by the bar 23, and in alignment with the socketsprovided by such bands. The member 39 is connected with the bar 23 by apin 21 extending through the eyes 4| and the sockets provided by thebands 29, the pin being held in position and removable in the samemanner as described for the construction shown in Figs. 1 to 5. Themember 39 is resilient and is so positioned that it constantly forcesthe bar 23 toward the whereby the pad has an even journal contacting"surface and uniform capillarity for delivery of lubricant uniformityovera `journal. The improvements also include a fabric cover for the padother than the journal contacting area, the cover being adapted toprevent grit or foreign particles in the lubricant from reaching therovings or capillary material whereby it is unnecessary to renovate thepad except at long intervals and such renovation is easily accomplishedwhen it becomes necessary.

Having thus described the invention, it is obvious that variousimmaterial modifications may be made in the same without departing fromthe spiritof the invention; lhence I do not wish to be understood aslimiting myself to the exact form, construction,- arrangement andcombination of parts herein shown and described or uses mentioned.
